What does Chapter 30 of the Sai Satcharitra say about Sai's nature and how he manifests for his devotees?

Chapter 30 of the Sri Sai Satcharita explains that Sai's essential nature is formless, or 'Nirguni.' However, through the power of the devotees' devotion and faith, this formless divine is drawn into a tangible form with attributes, known as 'Saguni.' The text beautifully states, 'through the qualities of devotees' devotion, You draw the formless into form with attributes.' This manifestation as a compassionate Guru, referred to as 'Karuṇālaya' (abode of mercy), is for the benefit of the devotees, as His 'Darshan dispels devotees' fear of worldly existence.' Thus, Sai's form is a loving response to the devotion of his followers.
